T all whom it may concern Be it known that l, Rmnmxo UsAKA, a.

I subject of the Emperor of Japan, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Antisli p ng Attechments for Shoes, Rubbers, or vershoes; and 1 do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in anti-slipping attachments for foot-wear.

My improvement may be applied directly to the boot or shoe, or to a rubber or overshoe. its object, as the title indicates, is to prevent slipping. it is adapted for use on ice as well as on all other slippery surfaces, or surfaces where the boot or shoe without such attachment, would slide or slip to such an extent as to make walking difficult. Hence, it may be employed to prevent slipping 9r sliding on sloping or inclined surfaces, as in mountain or cliff climbing.

The anti-slipping feature of my improvement is adapted to be located within the shank or upward curve of the boot or shoe, between the heel and the forward part or sole proper. llt consists of a block adapted to enter said recess directly forward of the heel, its'body portion being somewhat thinner than the heel. This body portion is equipped with pointed projections or "spikes which, when projected, extend below the heel a sutlicient distance to perform the antislipping function. These projections or spikes are secured to a plate located within the body member and acted upon by a spring, whereby the spikes are normally pro ected. This plate, however, is capable of being raised and secured against the action of its spring, whereby the spikes may be withdrawn, or raised sufhciently to prevent their interfering with the use of the shoe under ordinary circumstances, or where the necessity for the performance of the anti-slipping function is not present. Hence, the device may be worn without difiiculty at all times, since by virtue of the adjustable feature, the anti-slipping projections or spikes may be readily thrown into either the active or inactive position.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which its-illustrated an embodiment thereof.

In this drawing, Figure 1 is a side elevation of a shoe equipped with my improve ment, the spikes being shown in the projected position. Fig. 2 is a perspective View of one form of strap for retaining the device in place upon the shoe. Fig. 3 is a detail view of the anti-slipping feature. Fig. 4 is a view similar to Fig. 1, but showing a different form of strap or device for retaining the anti-slipping element in place upon the shoe. Fig. 5 is a perspective view of the form of securing-strap shown in Fig. 4:. Fig. 6 is a view similar to Fig. 3, but showing a slightly modified form of construction, being in fact, the form illustrated in Fig. 4. Fig. 7 is a. side elevation illustrating the device applied to a rubber or over-shoe, the latter being shown applied to the shoe proper. Fig. 8 is a vertical section of the anti-slipping element shown on a larger scale, the spikes being shown in the projected position. Fig. 9 is a section similar to Fig. 8, but showing the spikes withdrawn and locked in such position. Fig. 10 is an underneath view of the anti-slippin element of the device. Fig. 11 is a perspective view of the spring which normally acts to project the spikes.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the anti-slipping feature of my improvement, the same consisting of a body member h and a plate 7 carrying spikes or brads 8, the plate being acted upon by a relatively stiff spring 9 located within the body member, which is formed hollow for the purpose. The lower edge of the body member has an inwardly projecting flange 10 extending entirely around the same, and which forms a stop to the outward movement of the plate 7, whose edge bears against the flange 10. The spring 9 is under sufficient tension when the spikes are forced outwardly to their limit of movement to maintain the spikes in their operative relation with the surface over which the useris traveling. A. rod 12 passes through slots 13 formed in the opposite, sides of two of the walls 14 of the body member. The upper extremities of these slots are curved, as shown at 15, whereby when the rod 1% which is in contact with the lower surface of the plate'T, is moved upwardly and the plate 7 actuated (see Fig. 9) to withdraw the spikes 8 from their operative relation with t e surface u on which the shoe rests, as the rod is move slightly laterally, it will occupy the curved portion of the slots, whereby the plate 7 wlll'be locked against downward or outward movement. When, however, it is desirable to allow the spikes 8 to be projected, the pin is moved toward the left, (referring to the drawing), sufliciently to'bring it into alinement with the straight or vertical position of the slot, when the action of the spring 9 will force the plate 7, together with the spikes 8, to their outward limit of movement. The portions of the rod 12 near the extremities of the latter, normally engag the closed lower extremities of the slots 13, the lower edges of the walls It of the body member being depressed as shown at 16, for the purpose. The extremities of the rod 12 are exposed on opposite sides of the body member and equipped with milled heads 17* to facilitate adjustment. The opposite sides 14 of the body member are exteriorly equipped with buttons or headed pins 18, which are ada ted to be conne ctedwith means for atta'c ing the-antislipping device to the shoe, rubber or overshoe, as may be desired.

.' In the form of construction shown in Figs. 1 and 2, a strap 19 composed of two members 20 and 21, is employed, the said members being connected by means of a buckle 22 on one member and a perforated part 23 formed on the other member. This strap 19 has bifurcated extremities 24 having button holes 25 adapted to be connected with the buttons 18 of the body member. As

illustrated in the drawing, where the strap 19 is used, the latter passes around the shoe in the rear and is tightened through the medium of the buckle and its coiiperating strap part. In this event, the forward buttons 18 are slightly more elevated than the rearwardly located buttons.

In the form of construction shown in Figs. 4 and 5, a strap 26 is employed, This strap is constructed to pass around the instep of the shoe, and is arranged to be buckled in the rear through the medium of a perforated part 27 adapted to engage a buckle 28. This strap is provided with two depending bifurcated parts 29, having button-holes 30 adapted to engage the buttons 18 of the body member. In this case, the buttons may be both located at the same elevation.

In the form of construction shown in Fig. 7, the buttons 18 are connected with lips 31, provided with button-holes, the said lips bemy; formed integral with the body of the rubber or over-shoe 32. In the construction memos illustrated, the rubber is of the form whose rear portion is o ento allow the heel and the shank ofthe' s oeto protrude, thus making it practicable to locate the anti-slipping Having thus described my invention, what I claim 1s,-- 1

1. The combination of a hollow body member closed except at the bottom, a plate located therein and provided with projecs tions, a spring above the plate, means con-f nected with the body member for limiting the outward movement of the plate under the influence of the spring, and a rod engaging the plate from below, the said body member having slots formed in two opposite sides thereof and through which the rod passes, the lower extremities of the slots bemg closed to limit the outward movement of the rod, the upper extremities of the slots being curved to retain the rod at its upward limit of movement.

2. The combination with a boot or shoe,

of a hollow block adapted to enga e the shank of the shoe,

a sprm actuate plate located therein, g

and provided with antislipping projections, means for changing the position of the plate to cause the outer ex--' low block adapted to engage the shank of' the shoe, a spring actuated plate located within the block and provided with antislipping projections, means for vertically changing the position of the plate to vary the plane of the lower extremities of the rojections, and means for attaching the b ock to the shoe, substantially as described.

4. The combination with a boot or shoe, of a block adapted to engage the shank of the boot or shoe. a plate located within saidblock and movable up and down therein, the

said plate provided with projections normally extending below the heel of the shoe,

means for securing the plate the raised position, and means for attaching the block to the boot or shoe.
